System, devices, and methods for coupling portions of a medical device handle are provided. A male portion (202) and a female portion (204) of the handle may be coupled together using a sealant (244) such as room temperature vulcanized silicone rubber (RTV) using in conjunction with ultrasonic welding. The RTV may be applied to one of the male or female portions and the portions may be joined using a tongue (215) and groove (2259 connection, displacing the RTV from the weld site. The RTV helps to seal the bondline (206) after ultrasonic welding.

The invention provides a method of forming a wind turbine blade. The blade has a main blade module that defines a main body of the blade and includes a first mating feature, e.g. a tongue. The blade also includes a separate edge module that defines at least part of a trailing edge of the blade and includes a second mating feature, e.g. a recess. The method includes applying an adhesive to at least one of the first mating feature and the second mating feature. The method includes arranging the separate edge module relative to the main blade module such that the first and second mating features are mutually adjacent. The method includes applying a pressure force to squeeze the adhesive to bond the first and second mating features together. The pressure force is caused by removing air from, or injecting air into, an air sealed region.

A liquid storage bottle includes a bottle body having a resin-made first cylindrical part at one end, the first cylindrical part having an opening at its front end, and a tubular nozzle for pouring out the liquid contained in the inside of the bottle body by way of the opening, the tubular nozzle having a resin-made second cylindrical part bonded to the bottle body. The inner peripheral surface of the second cylindrical part is welded to the outer peripheral surface of the first cylindrical part. The outer peripheral surface of the first cylindrical part is provided with an annular groove extending in the circumferential direction and the annular groove is made to contain a part of the resin that is molten during the bonding operation.

Disclosed herein is a piping system for an air conditioner, in which a refrigerant pipe being an air conditioning piping of a vehicle and a flange member are each made of a plastic material, and the refrigerant pipe and the flange member can be connected by laser fusing. That is, the present disclosure provides the piping system for an air conditioner, in which the refrigerant pipe and the flange member are each made of a plastic material having a vibration insulation effect and are connected by laser fusing which can prevent damage so that an effect of weight reduction and vibration insulation can be provided and a pressure loss of a refrigerant fluid can be minimized by maintaining a diameter of the refrigerant pipe to be constant with respect to an overall length of the refrigerant pipe.

This specification discloses an article of manufacture. The article of manufacture has at least one structural blank and at least one guide. The structural blank has a plurality of oriented fiber plies in a thermoplastic matrix. The guide has a plurality of random dispersed fibers in a thermoplastic matrix. The guide is affixed to the structural blank by injection molding and over molding the guide onto the structural blank. The article of manufacture can take a number of forms for use in industries such as aircraft, automobiles, motorcycles, bicycles, trains or watercraft.

A water valve, guide tube for a water valve, and associated method are provided. The water valve includes a housing and the guide tube is installed on the housing via laser welding. The guide tube and housing each provide axially facing mating surfaces which abut one another in a pre-bonded configuration. In a post-bonded configuration, a laser weld joint is formed at the interface between the mating surfaces. The joint forms a portion of an outer periphery of the housing.

A laser joining method and device includes a pressure-applying clamping device, which presses a first and a second workpiece against one another at least after the workpieces have been locally plasticized, and a mask having mask structures, which allow laser light to pass only in the region of the bonding contact faces, wherein at least the workpiece facing the laser source is formed by a three-dimensional molded part, which is not planar at least on the first contour side facing the clamping element and/or on the second contour side facing the second workpiece, and wherein the clamping element, with the bearing side thereof for the first workpiece, is adapted to the first contour side of the first workpiece. The mask structures are created on the bearing side of the clamping element facing the first workpiece or on the second contour side of the first workpiece facing the second workpiece.

A sprinkler assembly includes a sprinkler body and a tubular connection fitting. The tubular connection fitting includes a first end for connection to a fluid supply pipe and a second end with the sprinkler body inserted therein, the tubular member including an outer surface and an inner surface defining an internal conduit extending along a longitudinal axis, the inner surface of the tubular member includes a first stop surface spaced from the first end to define an insertion depth for the fluid supply pipe and a second stop surface to limit insertion of the sprinkler body into the second end. The first stop surface defines an annular channel for housing an end of the fluid supply pipe.

A biodegradable container including a unitary polymeric body element having a top portion and a cylindrical body portion. The top portion has a cylindrical neck wherein the cylindrical neck defines an inner surface and an outer surface. The container further includes a polymeric bottom element welded to the cylindrical body portion of the unitary polymeric body element. A polymeric cap defines an internal rim configured to be received by the inner surface of the cylindrical neck. The polymeric cap includes an external cover having an interior surface which may be tapered so that the outer surface of the cylindrical neck and the interior surface of the external cover form an inner seal. The interior surface of the external cover may also form an outer seal with the outer surface of the cylindrical neck when the polymeric cap is in a closed position.

Examples of the present disclosure relate to a method of manufacturing a container for a printing material. The method includes providing a first portion of the container comprising an opening circumscribed by an annular wall. The method then includes providing a second portion comprising an annular cavity, followed by joining the two portions by advancing the annular wall into the annular cavity by applying a compressive force in an axial direction of the opening, and temporarily rotating the first portion and the second portion relative to each other to fuse the first and second portions.
